I'd fail to believe it's Cold Iron's shooter due to the name of "Alien" instead of "Aliens", however with the Kojima visit and the timing of The Game Awards, I would guess this could be an early reveal. Kojima's been visiting studios recently to see game demos, so would make sense to visit Fox to see how this project is doing if he's a fan of the IP. Interested to know how far along it is since its only been in development for, what, two years at most?
The Game Awards tagline of "Worlds Will Change" is also suspiciously similar to "Building Better Worlds", along with the VHS screen in the original promo art that looks quite Aliens-y. Their promotional video's glitchy animation style is also very similar to that used in Prometheus.
